How do you keep the fun going at fairs in a country affected by frequent power cuts and blackouts? Simple, just hire a bunch of workers to dangle from the bars of manual ferris wheels to keep it in motion.

India’s human-powered ferris wheels recently made headlines in Western media after a video of one such contraption at a fun fair in New Delhi went viral on YouTube and various news sharing sites, but the truth is the phenomenon is very common in Asian countries where electricity is unreliable. Some fairs use generators or even car batteries to power ferris wheels, but the simplest and most cost-effective way to keep people entertained is to hire a couple of daredevils to climb a manual ferris wheel and dangle from its metal bars to keep it spinning. The simple installations are made up of a simple metal frame and a few open-air cages, and without a power source they look like non-functional decorations when not in use. But as soon as people climb in the cages and the fearless wallahs start working their magic, you get pretty much the same feeling as you would from a modern ferris wheel.

These zero-emissions rides may be good for the environment, but the same cannot be said about the safety of the riders and spinning wallahs. But then again, India is known for its death-defying stunts. Just take a look at the Well of Death or the cattle stomping ritual.
